18" wheels

Did you have a question?
Just general discussing really. I think the rears will work out fine. I'm already looking at set of billet 20mm hub centric spacers. The front I'm a little more skeptical because of the larger and longer hub register. Is it easier to bore the rim, the rotor hub, or find some funky hub centric combination spacer that goes from 71.5mm or 70.5mm?
